Although this all depends upon the culture and society that you come from, this is one of the most difficult things one might have to tell a parent.
The reason is that your parents have an idea about who you are in their brain and unless they are canny enough to have worked it out for themselves, this will be breaking the image they have of their child.
First, make sure that you catch them at a time when they are least worried about other things, this will not allow them to deflect the issue. Secondly, tell them both at the same time, so that they are not keep a secret from each other.
Remember that they may be very disappointed, they may suffer from shock homophobia, they may also be very rude, not believe you, mock you, any possible reaction. They may also already know, or completely accept you for who you are.
The important thing is to sit them down, tell them and then give them some space.
